System settings

All the following settings must be configured in PRO apps with access to the system settings. If you don’t have extended access or if it has expired, make a request to the hub owner. To do this, go to Devices tab and click the icon in the upper right corner of the screen. Select the time interval you need.

Test the system once a week.

How to set alarm duration

The alarm duration should be set in accordance with the following standards:

To change the siren settings in Ajax PRO app:

1. Go to the Devices tab.
2. Select the siren from the list.
3. Go to Settings by clicking the gear icon .
4. Click Alarm Duration and set the duration in accordance with the standard that you need.
5. Click Back to save the new settings.

How to disable force arming

Arming the system with malfunctions should be disallowed. You cannot activate the armed mode if the system integrity is violated. For example, a window is open in the protected facility. To arm the system, you should eliminate the malfunction first.

To disable force arming in Ajax PRO app:

1. Go to:

   Hub → Settings → Service → System Integrity Check.

2. If the toggle is disabled, turn it on.
3. Disable the Arming Permission toggle.
4. Click Back to save the settings.

How to configure LED indication

The British disco function should be enabled.
To configure the hub’s LED indication in Ajax PRO app:

1. Go to:

   Hub → Settings → Service → LED indication.

2. Choose British disco.
3. Click Back to save settings.

When the particular detector is detached from the surface or removed from the mounting panel, the red and blue LEDs flash in sequence for 5 seconds at the hub. More information about British disco LED indications you can find here.

How to enable Bukhoor mode

Bukhoor mode allows to deactivate smoke alarm events for 15 minutes. In this mode, fire detectors don’t send a smoke alarm to a CMS, but still notify about it with a built-in siren.

By default, the Bukhoor mode is disabled. It’s the installer’s responsibility to enable this feature during installation when this function is required by UAE National Regulation.

To configure the Bukhoor mode in Ajax PRO app:

1. Go to:

   Hub → Settings → Service → Fire detectors settings → Bukhoor mode.

2. Select at least one fire detector operating in this mode.
3. Click Save.
4. Enable the Allow Bukhoor mode toggle.
5. Click Close.

To pause smoke alarm events, go to the Control tab. For safety, pausing is unavailable from midnight to 7:00 am.

Only the HB2.P.J-000-EU/UAE and HB2.4G.J-000-EU/UAE hub model includes Bukhoor mode and is used for applications in UAE. It is listed under UL985 (UTOW) standard.

Installation requirements

Hubs and other devices should be installed in accordance with the following:

1. Manufacturer’s installation manual.
2. UAE Fire and Life Safety Code of Practice 2018.

Installation of an outside alarm device shall be governed by the Standard for Installation and Classification of Burglar and Holdup Alarm Systems, UL 681.

Burglar-alarm systems are classified by type of system. The types of systems covered by these requirements include central station, mercantile, bank, proprietary, and national industrial security systems. Requirements for residential burglar alarm systems are covered in UL 1641, the Standard for Installation and Classification of Residential Burglar Alarm Systems.

Owner’s instruction notice: “Not to be removed by anyone except occupant”.

The system should be checked by a qualified technician at least once every 3 years.

Smoke and heat detector locations

Selecting a suitable location is critical to the operation of smoke alarms. The figure shows some typical floor plans with recommended smoke and heat detector locations.

Follow these location guidelines to optimize performance and reduce the chance of false alarms:

• Before mounting alarms, program them into memory and perform a sensor test from the intended location to ensure reliable RF communication with the panel.
• Locate the alarm in environmentally controlled areas where the temperature range is between 5 and 38 °C and humidity is between 0 and 90% non-condensing.
• Locate alarms away from ventilation sources that may hinder the detection of smoke.
• Locate ceiling-mounted alarms in the center of the room or hallway, ensuring a minimum distance of 10 cm from any walls or partitions.
• Locate wall-mounted alarms with the top of the alarm situated between 10 to 31 cm below the ceiling.
• In rooms with sloped, peaked, or gabled ceilings, locate alarms 90 cm down or away from the highest point of the ceiling.
• When mounting alarms on suspended ceiling tiles, ensure that the tiles are securely fastened with appropriate methods to prevent displacement.

Do not mount the alarm to the metal runners of suspended ceiling grids. The metal runners can redirect the magnetic field of the alarm’s reed switch, leading to false tamper alarms.

Sending events to the CMS

Installers are responsible for verifying compatibility between the hub and the central monitoring station (CMS) used during installation. The installer shall verify the CMS’s compatibility with the system on a yearly basis.

There are four ways to transmit alarms to the CMS:

1. Via PRO Desktop app.
2. Via Ajax Translator app.
3. Via Cloud Signaling service (integrated into PRO Desktop app).
4. A direct connection.

The Ajax system can transmit alarms to PRO Desktop monitoring app, as well as to the central monitoring station (CMS) using SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other protocols.

When an alarm is received, the monitoring station operator of the security company knows what happened and where the rapid response unit has to be sent. The Ajax devices addressability allows you to transmit events, device type, its assigned name, and location (room, group) to PRO Desktop and the CMS. The list of transmitted parameters may differ depending on the CMS type and the selected communication protocol.
